WAC 296-96-05020   What requirements apply to the construction and fire safety of hoistway enclosures?  Generally, local codes and ordinances govern hoistway enclosure construction. When not in conflict with a local code requirement, the enclosure must:

     (1) Be built to a height of 7 feet above each floor, landing and adjacent stairway tread;

     (2) Extend (adjacent to the counterweights) the full height of the floor and 8 inches beyond the counterweight raceway;

     (3) Be constructed of either solid material or material with openings that will reject a 2-inch diameter ball; and

     (4) Be supported and braced so that it does not deflect more than 1 inch when subjected to a force of 100 pounds applied perpendicular at any point.

     (5) A full height hoistway enclosure is required only on the side(s) of the material lift for which the car is not equipped with a gate or enclosure.
